HARVESTER'.

SPECIFICATION forming part of Letters Patent No. 261,367, dated July 18,1882.

I Application filed February 17, 1882. (No model.)

To all whom it may concern:

' 7 Be it known that I, SAMUEL D. MADDIN, a citizen of the UnitedStates, and a resident of St. Paul, in the county of Ramsey and, Stateof Minnesota, have invented certain new and useful ImprovementsinHarvesters, of which the following is a specification.

My invention consists of certain improvements in harvesters, fullydescribed hereinafter, whereby the efficiency of the same is increased.

In the drawings, Figure 1 is a perspective view, showing mainly theconstruction of the frames. Fig. 2 is a transverse sectional elevationof the machine. Fig. 3 is a detached view of one of the bearing-bars.Fig. 4 is a' detached section through the cutter-bar. Fi g. 5 is aplan,the binder-platform removed. Fig. 6 is an elevation in section ofthe drivingwheel and adjuncts. Fig. 7 is a perspective view, showing thecutter-driving appliances.

Fig. Sis a diagram illustrating the connection of the driving-shafts,belts, cutter-bar, and elevators. Fig. 9 is a detached perspective viewof the butt-board.

The main frame A consists of the back bar, a, and the bars a a M, atright angles to the back bar, and socketed at their forward ends for thepassage of the front bar, b, which may height.

be solid orhollow, and on which also swings the frame B, consisting of aback bar, 1), parallel to' the bar If, connecting-bars I) b the sidebar, I), and arched frames 11 b, connected to the side bar, I), and tothe bar b as shown. Both frames are made of connected tubes, whichsecures strength with light weight, and the bar 11 may turn with theframe B or independently thereof. The main frame has a fixed axle forthe side wheel, 0, and bearings on the bars a o for the axle c of thedrivin g-wheel c. The main frame A carries the drivers seat A, and issupported at a uniform distance from the ground by the wheels 0 c. Theframe B, with the extension-frames b b b, which support the binderappliances, swings on or with the barb", and the latter, with thecutters 01-, may be turned so as to bring the cutters to any desiredangle to the ground to cut at any The tilting ofthe frame B is effectedby the driver through the medium of suitable appliances-for instance, alever, 1 hung to the bar a, and extending beneath the rear bar of theframe B, as shown.

The'grain-divider G is pivoted to the end of the bar b by the extensionof thelatter through a hole in the divider, whichis connected bya yoke,3, to the frame B, so as to move with the latter. The bar b is thecutter-supporting bar, and a bent strip, D, attached thereto by bolts 6forms at the rear a flange, e, and at the front a support, 6, for thecutters and guards. At theend of the bar b is an arm, I)", connected bya rod, b to a lever, b, by means of which the operator can turn the barto alter the angle of the cutters to the ground. The bar b may, however,be clamped so as to move temporarily with the frame B, or an arm fromthe bar 11 may extend to and be connected permanently to the frame A, sothat the motion of the frame B will not alter the angle of the cutters.

The frame B has bearings for two shafts,ff,

driven faster or slower than thebelt, so as tocarry the butts of thegrain faster or slower than the stalks, to bring the whole into properposition in the canvas to deliver it properly to the elevator. Endlesschains it pass round pulleys on shafts k 70 against which the grain is'pressed by a presser-plate, E, hung to a bar, 1, which may be turned bythe operator to raise or lower the plate, the lower end of which iscurved to permit the grain to pass between it and the elevator-chainsand condense and pack it against the latter, the body of the'plateholding the grain until it passes to the horizontal platform F of thebinder.

As the binding devices constitute the subject of a separate applicationfor Letters Patcut, I will not describe them here.

The means by which the movements are imparted to the belts,sprocket-chain, carriers, elevator, as wellas to the cutters, will bebest understood by the diagram Fig. 8.

The driving-wheel shaft 0 carries a pulley, c, from which a chain passesround a pulley, d, turning freely on the bar b and with miterteethengaging with those of a miter-pinion, (1 on a shaft, 01 Abelt passesround pulleys m mone on the shaft 01 and the other on the shaft f-andanother belt, it, passes round a pulley, n, on the shaft 76 and apulley, n, on the shaft f.

It will be seen that the belt or canvas h de rives its motion from thedriving-wheel a through the shaft of the latter, and the pulleys,wheels, and shafts c d d d m mf and roller 9, in the order named. Thesprocketchain derives its motion from one or other shaft, ff, accordingas the pulley i or i is clutched to its shaft, each pulley having aclutch-section, 8 which engages with a clutchseetion, s, sliding on theshaft, according to the position of a 1 -lever, s pivoted back of thebar If. This lever s is moved from the drivers seat by a lever, s. Thepulleyt' is larger than the roller 9 and pulley i, so that when thepulley i is clutched to the shaft the chain travels faster than thebelt, but when the pulley i is clutched to its shaft the chain is drivenslower than the belt.

The cutter-bar G is driven from a rock-shaft, H, the arm 1) at theforward end of which, or a cross-bar thereof, enters between two uprightstuds, q g, on the knife-bar, allowing plenty of play, so that thetilting of the cutterbar b or of the frame B does not interfere with thefree communication of the motion. I have found this connection to be amost effective one, as there is no strain of the parts, friction isreduced to a minimum, and all jerking is prevented.

The shaft H has at the rear another arm,p, that is connected by a pitmanto a wrist -pin on a crank-wheel on the end of a shaft, 19

driven from the main shaft 0 by miter-wheels It will be obvious thatother gears and devices may be used for moving the different partswithout departing from the main features of my invention.

The belt h is protected by a guard-plate, h, below it, and from the rearedge of the belt extends the grain-platform 7L2, hinged at its frontedge, so that it may be set at any desired angle to throw the grainforward or permit its being thrown back to bring it in proper positionfor the band and elevator to operate thereon without moving the binderappliances. The elevation of the platform It is effected by the operatorby means of a bar, h.

The guard 6, being a little higher than the sprocket-chain, serves toprotect the latter, as

also to enable the reel to bend back the grain properly.

As the binder-frame, elevator, grain -platform, and frame B swing rounda common center, 1), and as the pulley d, from which the other movementsare imparted, is on this center, the chan ge in position of the frame Bdoes not slacken or tighten the driving-belts,chains, or cables, and alldriving parts are maintained in proper relative position.

0 Figs. 2 and 9, is a butt-board secured to rods '6 connected andsliding in part of the frame, and provided with nuts, so that thedivider may be set forward or back to any position required to guide thegrain into proper relation to the elevators.

In order to maintain the rigidity of the frame, as well as take up anyslack from loosening of the joints, I combine with the frame at anydesired points a bent or double anglebrace, 8, supported centrally by anupright or bearing-for instance, the box-and extended at the ends to thesides of the frame through eyes, and provided with tightening-nuts, asshown in Fig. 3.

By the combination of the rectangular main frame and the arched frames1/ b all in one structure I secure great strength and rigidity withcomparative lightness.

I have shown and described levers for adjusting the different movableparts from the drivers seat. It will be apparent that other devices maybe used for this purpose.
